Problems solved by technology

[0005] Currently, extraction devices are usually used to extract platelet-rich plasma and platelet-poor plasma from centrifuged blood. However, existing centrifugal devices can only extract platelet-rich plasma or platelet-poor plasma. For plasma, platelet-rich plasma or platelet-poor plasma needs to be extracted again with the extraction device, which is inconvenient

Embodiment 1

[0032] Such as figure 1 Shown is a schematic structural view of the first preferred embodiment of the platelet-rich plasma extraction device according to the present invention, which includes a transparent piston dispenser 1, a first transparent liquid collector 2, and a second transparent liquid collector 4 And a transparent conduit, the transparent conduit includes an inlet end connected to the liquid outlet of the liquid distributor, a first free end 3 extending to the inside of the first transparent liquid collector 2 and extending to the second The second free end 5 inside the transparent liquid collector 4, the outer wall of the first free end 3 is in sealing connection with the liquid inlet end of the first transparent liquid collector 2, the outer wall of the second free end 5 is connected to the The liquid inlet end of the second transparent liquid collector 4 is sealed and connected, and the transparent conduit is provided with a three-way valve 6 at the position whe...

Embodiment 2

[0039] Such as figure 2 Shown is a schematic structural view of the second preferred embodiment of the platelet-rich plasma extraction device of the present invention, which differs from Example 1 only in that:

[0040] The push rod 8 includes a rod body and a cover body 9; one end of the rod body is fixedly connected to the back of the piston head 7, and the other end is fixedly connected to the cover body 9; the cover body 9 is socketed on the The outer wall of the cylinder is threadedly connected with the cylinder, so that the piston rod forms a rotary piston, and the operator can rotate the push rod 8 to make the piston head 7 move sealingly in the transparent piston type liquid dispenser, Realize the purpose of liquid propulsion. Moreover, the piston rod forms a helical advancing structure through the threaded connection, which can reduce the influence of disturbing the experimental results caused by the slight movement of the piston during the centrifugation process. ...

Embodiment 3

[0042] Such as image 3 Shown is a schematic structural view of a third preferred embodiment of the platelet-rich plasma extraction device of the present invention, which differs from Example 2 only in that:

[0043] The transparent piston-type liquid dispenser 1 is also provided with a liquid injection port 6, which is convenient for injecting or exporting liquid into the transparent piston-type liquid dispenser 1.

[0044] In another preferred embodiment of the present invention, as image 3 As shown, the top of the transparent piston type liquid dispenser 1 has a tapered structure, which is more convenient to control the flow rate of the liquid in the liquid dispenser.

Abstract

The invention discloses a platelet-rich plasma extracting device. The device comprises a transparent piston knockout, a first transparent liquid collector, a second transparent liquid collector and atransparent catheter, wherein the transparent catheter comprises an inlet end connected with a liquid outlet end of the knockout, a first free end extending into the first transparent liquid collectorand a second free end extending into the second transparent liquid collector, the outer wall of the first free end is connected with a liquid inlet end of the first transparent liquid collector in asealed mode, the outer wall of the second free end is connected with a liquid inlet end of the second transparent liquid collector in a sealed mode, moreover, a three-way valve is arranged in the position, connected with the inlet end, the first free end and the second free end, of the transparent catheter, an inlet of the three-way valve is connected with the inlet end, a first outlet of the three-way valve is connected with the first free end, and a second outlet of the three-way valve is connected with the second free end. Therefore, by controlling the there-way valve, platelet-rich plasmaand platelet-poor plasma can be extracted by means of the platelet-rich plasma extracting device, which is convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a platelet-rich plasma extraction device. Background technique [0002] After centrifugation, the blood will be divided into three layers, from top to bottom are platelet-poor plasma, platelet-rich plasma and red blood cells, of which: [0003] Platelet Rich Plasma (Platelet Rich Plasma, referred to as PRP), is plasma containing high-concentration platelets, which has the effects of rapid hemostasis, pain relief, and accelerated wound healing, and can greatly reduce the formation of postoperative scars. It is extracted from the patient's own blood, and after extraction and enrichment treatment, it can be used for the treatment of related diseases. Therefore, it has rich sources, convenient materials, simple preparation method and can be absorbed by the body. The use of self-PRP can avoid the problems of virus transmission and immune rejection. Therefore, PRP is widely u...
